1 Claim. (Cl. 19-67) This invention relates to a lint saver attachmentand, more specifically, a device for attachment to a lint cleaner whichprevents the unnecessary loss of lint and effects large savings ofcotton.

An object of this invention is to provide a lint saver attachment forlint cleaners that replaces the usual control bar assembly for retainingthe cotton in correct relation to the cylindrical saw assembly therebyeliminating the usual loss of the lint in present lint cleaners.

Another object of this invention is to provide a lint saver attachmentfor lint cleaners that is provided with a generally concave face fittingthe contor of the saws thereby positioning the cotton and guiding thecotton during action of the saws for saving lint and efiecting a savingof cotton.

A still further object of the present invention is to provide a lintsaver attachment for lint cleaners that is simple in construction, easyto install, eflicient in operation, well adapted for its intendedpurposes, and relatively inexpensive to manufacture.

These, together with other objects and advantageswhich will becomesubsequently apparent, reside'in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of a lint cleaner having the lintsaver attachment of the present invention installed therein whereinportions of the lint cleaner are broken away in section in order toillustrate the structural details and relationships of the variouscomponentparts of the present invention and the lint cleaner on whichthe lint saver of the present invention is attached;

Figure 2 is a detailed sectional view showing the lint saver attachmentof the present invention and its relationship to the periphery of thesaws;

Figure 3 is a perspective view of the lint saver attachment of thepresent invention;

Figure 4 is a perspective view showing one of the end brackets forsecuring the lint saver attachment of the present invention to a lintcleaner.

Referring now specifically to the drawings, it will be seen that thenumeral generally designates the lint saver attachment for a lintcleaner generally designated by the numeral 12. The lint. cleaner 12includes a brush assembly 14 rotating on bearings "16 and a saw cylinderassembly 18 rota-ting on suitable bearings supporting the saw shaft 20.A plurality of stripper bar assemblies 22 are provided for cleaning thelint cotton and the saws 18 are provided with a plurality of teeth 24that carry the cot-ton into contact with bars 24 to clean the lint afterwhich it is removed with the brush assembly 14. Feeder rolls 26 and 28are provided for the saws 18 and the lint saver attachment 10 of thepresent invention is positioned between the feeder roll 26 and the firstof the bars 22 for positioning the cotton against the saw teeth 24.

The lint saver attachment 10 includes a generally elongated plate 30having a concave surface for closely fitting 2,740,993 Patented Apr. 10,1956 around the saw teeth 24. One edge of the plate 30 is provided withan upturned right angular portion 32 and the other edge of the plate 30is provided with an upwardly curving and reversely turned edge 34.Adjacent to each end of the upturned portion 32 and the reversely curvedportion 34 is provided an elongated closed slot 36 for receivingfastening bolt 38 extending therethrough. The fastening bolts 38 engagethreaded apertures in an inwardly extending flange 40 on each end ofmounting bracket 42. The inwardly extending flanges 40 are provided withan upturning end portion 44 and a reversely curved end portion 46 thatis formed to fit into the inner contour of the plate 30 and the upturnededge 32 together with the reversely curved portion 34. The entire flange40 of the bracket 42 is positioned at right angles thereto. The for wardface of the flange 40 also is provided with a concave surface forfitting the rear convex surface of the central portion of the plate 30thereby providing a rigid support and rigid end pieces for the lintsaver attachment 10 thereby rigidifying the lint saver attachment 10 andproviding the means for easy attachment to the end walls of the lintcleaner 12 by providing fastening apertures 48 therein wherein suitablefastening means may be provided for securing the bracket 42 to the endwalls of the lint cleaner 12.

The lint saver attachment 10 of the present invention may be employed onlint cleaners 12 and substituted for the control bar that is normallypositioned between the smooth feed roller 26 and the stripper bars 22.The concave forward surface of the plate 30 forming the main bodyportion of the lint saver attachment closely approximates the contour ofthe outer edges of the saw teeth 24 wherein the saw teeth 24substantially pass under the plate 30 in a very close spaced relationthereby assuring the correct action of the saws 18 in relation to thecotton lint thereby effecting the positioning of the cotton on the saws.The lint saver attachment 10 does not change the normal operation of thelint cleaner and is easy to install on existing lint cleaners therebyeffecting a saving in the lint cotton and preventing the loss of lintusually occurring with the use of the presently available lint cleaners.Obviously, the lint saver attachment may be constructed of any suitablematerials meeting the necessary requirements for a device of this naturewherein it is rigid and reinforced by the right angular brackets 42wherein the inturned flanges 40 on the brackets 42 provide astrengthening reinforcement for the ends of the plate 30 therebyretaining the plate 30 in close proximity to the outer periphery of thesaws 18. The resultant efficiency in the lint cleaning operation willquickly defray the cost incidental to the provision and installation ofthe lint saver attachment 10 of the present invention wherein more lintcotton is produced during a given amount of time and using a givenamount of cotton.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly, all suitable modifications and equivalents may be resortedto, falling Within the scope of the appended claim.

What is claimed as new is as follows:

A lint saver attachment for lint cleaners having rotatable sawscomprising an elongated plate, a bracket on each end of said plate forattaching the ends of the plate to the lint cleaner, said plate having aconcave outer surface for positioning closely adjacent a portion of theperiphery of the saws, said brackets having an integral perpendicularlyextending flange about a portion of its periphery for attachment to theinner surface of the plate,

3 said plate having one longitudinal edge formed in perpendicularrelation to the main :body of the plate, and the other longitudinal edgei eversely curved for forming a smooth guide for the cotton, each ofsaid flanges on the brackets having an upturned edge and ,a Teverselycurved edge conforming'to and engaging the inner surface of the plate,said plate having longitudinal slots therein, and -fastening membersextending through the slots and engaging the brackets for adjustablymounting the plate on the brackets.
